[0037] The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] Refer to Figure 1 And Figure 2 As shown, the present invention provides a cold - pressing double - head device for assembling the bushing 600 into the automobile hood 500, which includes a workbench 100, a feeding unit 200, a fixing unit 300 and a press - fitting unit 400, wherein:

[0039] The workbench 100 is the support platform and control platform of the cold - pressing double - head device of the present application. The feeding unit 200, the fixing unit 300 and the press - fitting unit 400 are all arranged on the workbench 100. The control system in the workbench 100 controls the feeding unit 200, the fixing unit 300 and the press - fitting unit 400 respectively. Each unit coordinates with each other to realize the assembly process of feeding, fixing and press - fitting the bushing 600.

[0040] The feeding units 200 are arranged on the opposite sides of the workbench 100. The feeding units 200 on both sides transport the bushing 600 at the same time, which can improve the fixing speed of the bushing 600 and thus improve the press - fitting efficiency. Refer to Figure 3 As shown, the feeding unit 200 includes a feeding member 210, a first driving assembly 220, a first positioning seat 230 and a second positioning seat 240. The feeding member 210 is used to transport the bushing 600 into the first positioning seat 230, and the first driving assembly 220 is used to transfer the bushing 600 from the first positioning seat 230 to the second positioning seat 240. In the embodiments provided by the present application, the feeding member 210 can transport all the bushings 600 to the first positioning seat 230 one by one in an orderly manner. The bushings 600 in the first positioning seat 230 are sent into the second positioning seat 240 one by one through the first driving assembly 220, and then the fixing unit 300 fixes the bushings 600 in the second positioning seat 240 one by one.

[0041] The fixing unit 300 is correspondingly arranged with the feeding unit 200. There are also two fixing units 300. Each feeding unit 200 is connected to one fixing unit 300. The fixing unit 300 includes a moving plate 310, positioning posts 320 and a second driving component 330. The positioning posts 320 are arranged on the moving plate 310. The second driving component 330 is used to fix the bushing 600 in the second positioning seat 240 onto the positioning posts 320. In the embodiment provided by the present application, there are multiple positioning posts 320. The number and positions of the positioning posts 320 can be set on the moving plate 310 according to the specifications of the automotive hood 500. The second driving component 330 can move the second positioning seat 240 above each positioning post 320 according to the position of the positioning post 320, and install the bushing 600 in the second positioning seat 240 onto the positioning post 320.

[0042] The press-fitting unit 400 includes a first press-fitting component 410 and a second press-fitting component 420. The first press-fitting component 410 is used to press-fit the bushing 600 on the positioning post 320 into the automotive hood 500. The second press-fitting component 420 is used to press the automotive hood 500 and the bushing 600 in the automotive hood 500 tightly. In the embodiment provided by the present application, the first press-fitting component 410 can transfer the moving plate 310 to a position corresponding to the automotive hood 500, and assemble the bushing 600 on the positioning post 320 with the automotive hood 500. After all the bushings 600 are assembled, it is necessary to pressurize the automotive hood 500 through the second press-fitting component 420 so that all the bushings 600 can be tightly assembled in the automotive hood 500.

[0043] Based on the above embodiments, the working process of the present application is as follows: The feeding part 210 conveys the bushing 600 to be assembled into the first positioning seat 230. The bushing 600 is transferred from the first positioning seat 230 to the second positioning seat 240 one by one through the first driving component 220. Then, the bushing 600 in the second positioning seat 240 is fixed onto the positioning post 320 through the second driving component 330. After all the positioning posts 320 are fixed with the bushings 600, the first press-fitting component 410 assembles the automotive hood 500 and the bushing 600 on the positioning post 320 together. Finally, the automotive hood 500 is pressed down through the second press-fitting component 420 to be tightly pressed against all the bushings 600.

[0044] Refer to Figure 4 As shown, the feeding part 210 includes a vibrating feeder 211, a feeding channel 212, a first positioning rod 213, a second positioning rod 214 and a feeding pipe (not shown in the figure), where:

[0045] The first end of the feeding channel 212 is connected to the vibrating feeder 211, and the second end of the feeding channel 212 is connected to the first positioning seat 230. The first end of the first positioning rod 213 extends into the first positioning seat 230. The first positioning rod 213 is used to fix the bushing 600 in the first positioning seat 230. The feeding pipe is used to convey the bushing 600 on the first positioning rod 213 to the second positioning rod 214, and the second positioning rod 214 extends into the second positioning seat 240. In the embodiment provided by the present application, the vibrating feeder 211 can make the bushing 600 move one by one in the direction of the first positioning seat 230 through vibration. The bushing 600 in the first positioning seat 230 is sleeved on the first end of the first positioning rod 213 under the action of the first driving component 220 and can move along the first positioning rod 213 towards the second end of the first positioning rod 213. As the bushing 600 is continuously conveyed, the bushing 600 on the first positioning rod 213 is sent to the first end of the second positioning rod 214 and continues to move towards the second end of the second positioning rod 214 until it enters the second positioning seat 240. Then, under the action of the first driving component 220, the bushing 600 is moved to the installation position in the second positioning seat 240 where it can be fixed to the positioning column 320.

[0046] In a feasible implementation manner, the feeding pipe is a flexible pipe. The two ends of the flexible pipe are respectively connected to the second end of the first positioning rod 213 and the first end of the second positioning rod 214, so as to transfer the bushing 600 in the first positioning seat 230 into the second positioning seat 240. Since the second driving component 330 can drive the second positioning seat 240 to move, it is more convenient to convey the bushing 600 by using a flexible pipe as the feeding pipe.

[0047] Further, the first driving assembly 220 includes a first pushing cylinder 221, a second pushing cylinder 222, and a third pushing cylinder 223. The first pushing cylinder 221 is configured to push the bushing 600 within the first positioning seat 230 to the first end of the first positioning rod 213. The second pushing cylinder 222 is configured to push the bushing 600 at the first end of the first positioning rod 213 in the first direction D1 onto the first positioning rod 213. The third pushing cylinder 223 is configured to push the bushing 600 on the second positioning rod 214 into the second positioning seat 240. In the embodiment provided by the present application, the first direction D1 is the direction of gravity. When the bushing 600 reaches the first positioning seat 230, the first pushing cylinder 221 is activated to push the bushing 600 to the first end of the first positioning rod 213. Then, the second pushing cylinder 222 is activated. The piston rod of the second pushing cylinder 222 moves upward to push the bushing 600 upward so that the bushing 600 is sleeved into the bushing 600 at the first end of the first positioning rod 213. Then, the piston rod of the second pushing cylinder 222 retracts, preparing for the next upward push, thereby enabling the bushing 600 to move upward along the first positioning rod 213 one by one. As the bushing 600 moves upward, it enters the feeding pipeline and then reaches the second positioning seat 240. Then, the third pushing cylinder 223 is activated to push the bushing 600 at the second end of the second positioning rod 214 to the installation position.

[0048] Referring Figure 4 As shown, the first positioning rod 213 is a vertically arranged rod body. When the bushing 600 is sleeved on the first positioning rod 213, it will fall under the action of gravity. Therefore, a limiting member 250 is provided on the first positioning rod 213 to prevent the bushing 600 from falling back into the first positioning seat 230 under the action of gravity. Referring Figure 5 As shown, in the embodiment provided by the present application, the limiting member 250 includes a flipping plate 251, an elastic restoring member (not shown in the figure), and an opening 252 provided on the rod body of the first positioning rod 213. The opening 252 is arranged in the left-right direction. The flipping plate 251 is inclined and abuts against the inner wall of the opening 252. One end of the elastic restoring member is fixed to the first positioning seat 230, and the other end is connected to the flipping plate 251. When the second pushing cylinder 222 pushes the bushing 600 upward and overcomes the elastic force of the elastic restoring member, the flipping plate 251 flips away from the opening 252, and the bushing 600 can move upward along the first positioning rod 213. After the bushing 600 passes through the position of the flipping plate 251, the flipping plate 251 flips toward the direction close to the opening 252 until it abuts against the inner wall of the opening 252. Since the flipping plate 251 is inclined and abuts against the inner wall of the opening 252, after the bushing 600 passes through the abutting position, the flipping plate 251 blocks the bushing 600, thereby preventing the bushing 600 from falling back into the first positioning seat 230 under the action of gravity.

[0049] Referring Figure 3As shown, the second driving component 330 includes a first cylinder 331 and a first cylinder module 332. The first cylinder 331 is used to fix the bushing 600 in the second positioning seat 240 onto the positioning post 320, and the first cylinder module 332 can drive the first cylinder 331 to reciprocate along the second direction D2 and the third direction D3. In the embodiment provided in the present application, the second direction D2 is the horizontal front-back direction, and the third direction D3 is the horizontal left-right direction. When the bushing 600 reaches the installation position of the second positioning seat 240, the piston rod of the first cylinder 331 moves downward to push the bushing 600 in the second positioning seat 240 onto the corresponding positioning post 320, and the first cylinder module 332 drives the first cylinder 331 to move in the front-back and left-right directions within the horizontal plane, so as to realize the fixed installation of multiple positioning posts 320 and bushings 600.

[0050] Referring to Figure 6 and Figure 7 As shown, the first press-fitting component 410 includes a second cylinder module 411, a second cylinder 412, and a fourth pushing cylinder 413, where: the second cylinder module 411 is used to drive the moving plate 310 to reciprocate along the second direction D2; there are two second cylinders 412, and the two second cylinders 412 are symmetrically arranged on both sides of the second cylinder module 411 along the third direction D3; there are two fourth pushing cylinders 413, each second cylinder 412 is connected to a fourth pushing cylinder 413, the second cylinder 412 can drive the fourth pushing cylinder 413 to reciprocate along the first direction D1, and clamping blocks 414 are provided at the ends of the piston rods of the two fourth pushing cylinders 413, the two fourth pushing cylinders 413 are arranged oppositely, and the two clamping blocks 414 jointly clamp the automotive hood 500.

[0051] In the embodiment provided in the present application, the second direction D2 is the horizontal front-back direction, and the third direction D3 is the horizontal left-right direction. After all the positioning posts 320 are fixed with bushings 600, the second cylinder module 411 transfers the moving plate 310 to the position for press-fitting with the automotive hood 500. Before press-fitting, the two second cylinders 412 are activated to drive the corresponding fourth pushing cylinders 413 to move upward. The automotive hood 500 to be assembled is placed between the two opposite fourth pushing cylinders 413. The two fourth pushing cylinders 413 are activated simultaneously, and the two clamping blocks 414 move simultaneously in the direction close to the automotive hood 500 until the two clamping blocks 414 clamp the automotive hood 500. Then the two second cylinders 412 are activated again to drive the fourth pushing cylinders 413 to move downward, and the automotive hood 500 is press-fitted onto the positioning post 320, so that the bushing 600 and the automotive hood 500 are initially press-fitted.

[0052] After the initial press-fitting is completed, the bushing 600 and the automotive hood 500 need to be further tightened through the second press-fitting component 420 to achieve complete assembly. Referring to Figure 8As shown, the second press-fitting assembly 420 includes a pressing cylinder 421, a pressing rod 422, a support platform 423, and a guiding member 424, where: the pressing cylinder 421 can drive the support platform 423 to reciprocate along the first direction D1 through the guiding member 424, the pressing rod 422 is arranged on the side of the support platform 423 facing the workbench 100, and the pressing rod 422 is used to press the vehicle hood 500 and the bushing 600 inside the vehicle hood 500 tightly.

[0053] In the embodiment provided by the present application, after the bushing 600 and the vehicle hood 500 are preliminarily assembled, the two second cylinders 412 are started again to drive the corresponding fourth pushing cylinders 413 to move upward. Then, the piston rods of the two fourth pushing cylinders 413 retract simultaneously, and the clamping blocks 414 at both ends of the vehicle hood 500 move away from the vehicle hood 500 respectively under the drive of the fourth pushing cylinders 413, thereby releasing the clamping of the vehicle hood 500. Then, the second cylinder module 411 is started to drive the moving plate 310 to move below the second press-fitting assembly 420. A plurality of pressing rods 422 are arranged below the support platform 423. When the pressing cylinder 421 is started, the support platform 423 moves downward along the guiding member 424, so that the plurality of pressing rods 422 press against the vehicle hood 500, and the vehicle hood 500 is further pressed tightly against the bushing 600. In a feasible implementation manner, the guiding member 424 includes a guide post 4241 and a guide cylinder 4242. The guide cylinder is arranged on the support platform 423, the guide post 4241 is sleeved in the guide cylinder 4242, and the guide post 4241 is fixed to the workbench 100. When the pressing cylinder 421 is started, the support platform 423 can move downward under the cooperation of the guide post 4241 and the guide cylinder 4242. In order to ensure the stable movement of the support platform 423, four guide posts 4241 and four guide cylinders 4242 are provided, and the four guide posts 4241 and the four guide cylinders 4242 are evenly distributed at the four corners of the support platform 423.
